Justin Timberlake Performs " Let the Groove Get In" on Jimmy Fallon"

Every artist who has a catalog of songs has that one song that ends their show. 

You know, that "Baby I'm a Star" moment in Purple Rain that makes the crowd feel good when they go home (even though Prince didn't like the movie's ending).

For the Rolling Stones it is "Satisfaction".

For Janet Jackson its "Together Again".

For Justin Timberlake that song might be "Let the Groove Get In."

Sounding like a song the Neptunes could have produced for Timeberlake's first solo effort "Justified", the partying "Groove" is one part Michael Jackson's "Wanna Be Starting Something", another part Lionel Richie's "All Night Long".

"Groove" is basically a feel good, high energy song that should seem out of place in this EDM era of music, but inactuality  it might be the shot in the arm that needs to bring more musicality and instruments back to pop radio.
